ASTM C1749

Full Name

ASTM C1749 – Standard Guide for Measurement of the Rheological Properties of Hydraulic Cementious Paste Using a Rotational Rheometer


This guide covers description of several methods to measure the rheological properties of fresh hydraulic cement paste.

All methods are designed to determine the yield stress and plastic viscosity of the material using commercially available instruments and the Bingham model. Knowledge of these properties gives useful information on performance of cement pastes in concrete.
